A new feature coming with an update will now allow you to pin your favorite conversations to the top of your chat list on WhatsApp. The "pin post" feature as of now is available to WhatsApp beta users only. But you can also enjoy the feature by downloading the WhatsApp beta for Android and iOS.
Users with WhatsApp beta 2.17.162 or 163 versions can use the feature. The feature is in its testing stage and will be rolled out to the Android users and later for the iOS users.
When you pin a chat, it will show on the top of your chat list. Even above recent WhatsApp chats with other individuals and groups, you will see them after these pinned chats.
The new feature is a pretty handy one as one could get tired of scrolling through chat lists to find a recent conversation.
To download WhatsApp beta, sign up for WhatsApp “Beta” on Google Play store from your Android phone and then update it, and voila! You're set to pin chats.
To use the feature, hold or long-press on the individual/ group chat you want to pin to the top, and choose the Pin symbol from the top bar. The other options alongside Pin are Delete, Mute, and Archive.
Also, you can unpin WhatsApp chats whenever you want, by long pressing the option, and disabling the Pin button. Remember that the feature is in testing stage and not available for the regular WhatsApp version. Hopefully, once it's stable and finalised, it would be rolled out to everyone.
